HDMI® Output in Lenovo® ThinkPad T410 Laptop
Lenovo ThinkPad T410 is a laptop which is targeted at business users. It comes with a new line of dedicated and integrated graphics cards and the Intel Core series processor. It also offers very good connectivity, including 802.11n Wi-Fi, gigabit Ethernet and inbuilt mobile broadband. It contains lots of ports including FireWire and eSATA. HDMI means High Definition Multimedia Interface, which is a compact audio/video interface for transmitting uncompressed digital data. HDMI is electrically compatible with DVI signals. So no signal conversion is necessary and there will not be any loss of video quality when a DVI-HDMI adapter is used.
- Interoperability issues
- No closed captioning
- Sound issue
Interoperability problems are mainly caused by the manufacturer’s improper or incomplete information of the technology. HDMI connected components might cause some incompatibility. Beyond the initial handshake there are possibilities of miscommunication between the components. The HDMI output will also require the right drivers for the proper functioning of the connected devices. It is recommended that the drivers should be updated periodically.
No closed captioning
The HDMI output in Lenovo ThinkPad T410 does not include any requirement for carrying closed captioning data. So if you connect a video component like an HD cable or DVD/Blu-ray Disc player you will not see conventional closed captions. If you need to view closed captions, use a component video connection then the closed captions will pass through and you can still enjoy a high definition picture.
HDMI incorporates an intelligent two-way communication channel between components, but sometimes it might give rise to audio problems. Unfortunately they are not designed to pass audio through the HDMI connection and they perform video switching only. In order to use multichannel audio from the receivers you need to connect an optical or coaxial digital cable from your video source to the receiver. All the HDMI equipped components are designed to turn off digital audio outputs when the HDMI output is in use.
